Middle-10 team parlay

[Kathy]

I am a "for fun" sports better. I have a 10 Leg Parlay Card (cost $10) with 5 winners in, 5 games to go. (pays $ 6,000 - I know parlays are sucker bets)

Games left: South Carolina -6, game on 12/29, Michigan +1, game on 01/01, Boise State +8, game on 01/01,
LSU -9, game on 01/03, Ohio State -8, 01/08.

At what point do I start to bet the other side to insure a "win". What amount?

thanks,

Kathy
